Face Pixelation....

decob

Just looking for some pointers/tutorials if possible on creating that blurred/pixelation look you see when you are trying to hide someone's face on tv.

Whats the best way to do it? after effects & keying an adjustment/mask layer? or is motion tracking the way to go?

or is something like that easier to do in the likes of flame?

Key framing it is probably an easy way to do it, as face tend not to have too much non-linear motion, I assume the person is walking or just sitting still?

The effect will be already in the effect palette (Mosaic or some-such) Just play with the settings.

Some software packages have keyframe tracking abilities next to worthless when theres piles of movement, then get lost too easily.

what application are you using? There's a cheap motion tracking plug-in for final cut express/pro that's the biz. from a pc point of view I exported a motion clip to a filmstrip, imported into photoshop and created a mask that way - but I'm sure someone else has a better way

Well it depends. If for example you're tracking a point moving in a fluid straight line, the motion tracking software should be okay.

Decob sounds like it someone who moves rapidly across screen, moving in an indiscriminate manner, (like a drunk being arrested who's face needs blurring)

Seriously try it with something like that and any keyframe tracker, just goes to pieces.

i ended up using after effects and manually keyframing it, i tried the motion tracking but that was taking ages, plus osme of the footage i had to doctor was ex-Vhs, quality was crap and the tracker went all over the place.
